IMPROVED BRICK-MACHINE.

l The Schedule Vreferred to in these LettersPatent and making part of the name.A

To all whom it may concern:

Beit known that we,REMBRANDT Lockwoon and CHARLES O. SCHMITT, of the' city, county, and State of New York, have invented a new and useful Improvement in Brick-Machines; and ive4 do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled .in

- the art to make and use the same,reference being had tothe accompanying drawings, forming part of 'this specification. v This invention relates to improvements in brickmachines, whereby it is designed, by the employment of a sliding clay-receiver, reciprocating moulding-apparatus, and delivering-carrier, arranged to receive the clayfrom the bottom of the mill, and carry it to the vertically-reciprocating moulding-apparatus, where it is mouldedandv delivered to the delivering carryingapparatus, which delivers the moulded bricks from-"the mill, to provide an improved and simple apparatus forV accomplishing the ,moulding and pressing oi bricks.

In. the accompanying drawings- Fignrel represents a plan view of a part of the vapparatus for removing the moulded bricks.,

. Figure -2 represents the device for operating the. same;

Figure ,3 represents a side view of our improved machine, with some parts shown in section. Y Figures 4 and 5 represent the clay-carrying table in plan and section.

Figure 6 represents a section of the pressing and l moulding-apparatus. v c Figure 7 represents the face of the moulding-appa ratus. Y i A v Figure 8. is a detached sectional view, showing the means for removing, from `the reservoir, the boards upon which the bricks are carried from the moulds to the endless carrier, to, discharge them from the machine. r

Similar letters of reference indicate corresponding parts.

A representsa clay-grinding and mixing apparatus, of ordinary construction, having a passage, D, through the bottom, and arranged above a sliding carrier, B, having a recess, a, provided with Aan adjustable bottom for'receiving the clay through the said .passage D.

Ato-and-fro motion is imparted to the carrier by means of a shaft and pinion, operated by the pulley C, which derives motion from the wheel O, having an oscillating motion imparted to it from the verticallysliding, pressing, and moulding frame, working in the vertical guides H, the same being connected by the links N, and the said pinion working in a rack on the under side ofthe carrier B.

The moulding-frame is operated by a walking-beam, 4I, operated from the driving-shaft, or it may be operated by any other competent means.

The carriage B, and the means for operating it, are so adjusted, with reference to the moulding-apparatus, that when the latter is in its most elevated position, the recess c, of the carrier, will be inthe position to receive'a charge of clay from the mill through the passage D, and the downward movement'of the mouldingframe will cause the carrier to belmoved under the said frame, sufliciently in advance of the completion of the movement of said'moulding-frame, to allow the .moulding-apparatus to act on the clay in the said carrier, to form it intro bricks, as follows, the clay being sufficiently condensed as it is pressed into the said recess:

c' represents moulds, projecting downward om the mould-carrying slide H', in a manner to be forced into the clay in the recess a, and thereby separate and shape it into the desired form.

L represents plungers or followers, connected to the adjustable bar J, and arranged to work vertically in the said moulds, serving as a means toi 'eii'ect the delivery ofthe brick out of the moulds, after having been vcarried up by the moulds to which they adhere.

In vthe downward movement of thefslide H", the bar J will st rikethe ledges K ofthe guides H, and thereby be arrestedin its movement, while the moulds are continued to the bottom of the recess a.'

When the slide H rises, the ends of the bar' J. strike corresponding ledges or stops, P, onthe guides H, and thereby arrest the movement 'of the plungers, and cause them to discharge the moulded brick from the moulds a', which continue sufiiciently in their ascent to insure theaccomplishment of the same. I

- T represents another carrier, arrangedV to receive the brick when so discharged from the mouldsand deliver them out of the machine. It is arranged to slide in ways, and a to-and-fro motion imparted to it from the wheel .0, in a manner similar to that by which the carrier B is operated. c

It is provided with swinging catches, K2, which, on the inward movement of the same, 4pass through the bottom of a reservoir, B', arranged above the said carrier, and take therefrom the lowermost board, R, of'a series, which is kept supplied to the 4said reservoir, and cause it to be carried under the moulds, just previously to the dropping of the brick, to receive them, on which they are carried back, by thel return movement of the carrier T, to such a position that the projecting edge of the board will be canghtby the endless chains, working over the rollers X X, and be by them delivered to the table T', from which they may be taken away.

The swinging catches K2 are thrown down b'elow the "board R, by their pendent 'parts istriking against the rst roller X', as shown in red, iig. 8, to allow the boards to be carried off by the chains, and the remaining 'boards in the reservoir may be prevented from falling down suitable latch-mechanism, to be actuated at the ccmmencement of the inner movement of the carrier T.l

The carrying-chain rollers XX maybe operated by a b'elt from the driving-pulleys Z' Z, or by any other means suitable to give a continuous rotary motion.

AtF and G we have represented in outline a mechanism for sanding the recess a and the carrying-boards, consisting of'a shaking sand-box, G, arranged to be agitated by atoppel-wheel, F, having, on its shaft, cogwheels, gearing into racks on the upper face of the carrier B, and deriving motion therefrom; but we make no claim of this arrangement of sanding-mechanism.

The bottom of the "recess aI may be adjusted, for the purpose less amount of clay, and the stops K and P may be adjusted on the guides H.

The positionof the mould-boxes cb may be also adjusted on the frame H', all as may be desired,l for the 'purpose of regulating the thickness of the moulded bricks, and the'amonntvof pressure to be imparted to them.

within the range of the' 'catches by any` of varying its capacity to receive a greater or.

claim as new, and desire to secure by Letters Patenth 1. The arrangement of the followers L with the moulds a', the bar J, frame vH', and the adjustable stops'K and P,all substantially as and for the purpose specified. I 2` Thercombination, with the reciprocating moulds a', followers L, and the grinding-apparatus Aof the reciprocating carrier B, havinga recess, a, substantially as and for the purpose specified.

ing moulds a', of the carrier T and the endless chains, substantially as and for the purpose describedA 4. The combination, with the carrier T, provided with the swinging catches K2, of the reservoir R' and carrying-boards 1t, substantially as-and' for the purposev described. l
